To upload a video longer than 1 minute on Instagram, use Reels (up to 15 minutes), or post it as a regular video (up to 10 minutes for most, 60 for larger accounts). Go to the + icon, select your video, and Instagram will guide you to post it as a Reel or split it into 1-minute segments. For even longer content, use Instagram Live (up to 4 hours) and save it afterward.
